Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.

2015 Toyota Prius C is still colorful, still gets 53 mpg

Few vehicles can match the affordable fuel economy of the $19,000, 53-mile-per-gallon Toyota Prius C, and that fact isn't likely to change for 2015, as the Japanese company has issued a moderate refresh of its sub-compact hybrid.
As mid-cycle refreshes go, this is a pretty standard affair, with a larger grille and tweaked LED headlights at the front of the Prius C, and more expressive taillights at the back. Toyota made some minor changes in the cabin, updating materials throughout, but not fiddling too much with the overall level of equipment.
Aside from those modest changes, this is the same fuel-efficient five-door, retaining its 1.5-liter, 73-horsepower, 82-pound-foot four-cylinder, while an electric motor tosses in an extra 26 ponies, for a total system output of 99 horsepower. Along with the 53-mpg highway rating, the C will return 46 mpg in the city.
